PURPOSE: To provide a means to correctly control the flow rate of a fuel in a fuel flow device to continuously circulate the fuel to an after burner or the like through a disbursement means. CONSTITUTION: An improved augmentor fuel supply system includes a fuel source 110, a pump 120 to apply the pressure to a fuel, a flow rate control means 130 to control the flow rate and the pressure of the fuel toward a fuel disbursement means 140 (for example, augmentor), and a return path to re- circulate the unburnt fuel. The flow rate control means includes a restrictor means 132 like a small orifice parallel to the control valve 134. This restrictor means capable of flowing the fuel to the fuel disbursement means when a control valve is closed. In addition, a second restrictor means 150, for example, a small orifice, is included in the return path. Finally, a non-return valve 160 is included in the return path to prevent the fuel from flowing into the augmentor through the return path.
